Q

what is metabolism?

A

a collective noun; it is all of the chemical reaction sand physical process that take place within the body. This includes growing, repairing, reacting and reproducing.

19
Q

what is homeostasis?

A

reflects the ability of the body to maintain a relatively stable metabolism and to function normally despite changes.

20
Q

what is a negative feedback mechanism?

A

the body’s response reverses the stimulus (in effect, turning it off for a while) and keeps some aspect of the body metabolism wnl.

21
Q

what does Thyroxine do?

A

stimulates the cellular enzyme system that produce energy from food, which increases metabolic rate.

22
Q

what is a positive feedback mechanism?

A

response to the stimulus does not stop or reverse the stimulus but instead keeps the sequence of the events going. It requires a Break, to interrupt it, therefore they can be self-perpetuating
> more rare in human body. ex child birth, fevers d/t bacteria, blood clot etc.

23
Q

What are some examples of body systems that are regulated by negative feedback?

A

secretion of hormones
HR
BP

24
Q

what is anatomic position?

A

standing up right, facing forward.

25
Q

what are the two major cavities of the body?

A
  1. dorsal (posterior)

2. ventral (anterior)

26
Q

what is contained in the dorsal cavity?

A
  1. CNS, > cranial cavity and the vertebral/spinal cavity
27
Q

is the dorsal system continuous or bound into separate subdivisions.

A

continuous

28
Q

what is included in the cranial cavity, and the spinal cavity?

A

cranial >formed by skull and contains the brain

spinal> backbone and spinal cord

29
Q

what membrane lines the dorsal cavity?

A

meninges

30
Q

the ventral cavity is comprised of which two compartments?

A

the thoracic cavity and the abdominal cavity

31
Q

is the ventral cavity continuous or bound into separate subdivisions?

A

bound by the diaphragm

32
Q

what organs are included in the thoracic cavity, and what is the membrane that bounds it?

visceral pleura

34
Q

what membrane covers the heart?

A

pericardical membranes

35
Q

what organs are included in the abdominal cavity

A

liver, stomach and intestine.

36
Q

which two serous membranes cover the abdomen cavity?

A

peritoneum (entire abdomen wall) and mesentery (cont’ membrane folded around and covering the outer surface of the abdomen organs.

37
Q

what organs are included in the pelvic cavity?

A

urinary bladder, reproductive organs,

38
Q

A

frontal (coronal) section

39
Q

41
Q

which plane cuts along the long axis of an organ

A

43
Q

what is a quadrant (in terms of planes)

A

a transverse plane and mid-sagittal plane that crosses the abdomen into 4 quadrants.

44
Q
